Hi! Thanks for posting the outputs... Seems like your fstab is ok and it's trying to mount MyDocs on startup and on what I can see is /dev/mmcblk0p1 is having some issues which causes it to fail to mount. And another question... Did you reformat MyDocs using a PC? What I had in mind is you might have formatted it to exfat or something else...

So for now could you download this fdisk I will attach?
download it then extract, become root, copy fdisk to /usr/sbin, then do chmod 777 /usr/sbin/fdisk then type fdisk then when you're in fdisk console type p enter and paste here output
